DRV8308: Termination of ENABLE, BRAKE and DIR in case of unuse

Hirotaka Matsumoto

Part Number: DRV8308

Hi all

Would you mind if we ask DRV8308?

Could you let us the termination of ENABLE, BRAKE and DIR in case of unuse?
Is it possible to set open?

Kind regards,

Matsumoto-san,

ENABLE, BRAKE and DIR has an internal pulldown resistor. When you leave them open, they are logic low due to the internal pulldown resistor. The 100kohm pulldown resistor description and value can be found in datasheet Page 3 and Page 8.
